What is the JJ Smith Green Smoothie Cleanse?

How Long Should You Do the JJ Smith Green Smoothie Cleanse?

The JJ Smith green smoothie cleanse is designed to be followed for 10 days. This timeframe allows the body to begin eliminating toxins, burning fat, reducing cravings, and experiencing the full detoxifying benefits.

JJ Smith does not recommend doing the cleanse for longer than 10 days. Following a restricted diet for too long can cause nutritional deficits, fatigue, and metabolism issues.

Here are some tips on how long to follow the JJ Smith green smoothie diet:

  • Beginners should start with the 10-day cleanse to ease into the program.
  • You can repeat the 10-day cleanse up to 4 times per year, allowing at least 2 weeks between cleanses.
  • Listen to your body and stop the cleanse if you feel overly fatigued or hungry.
  • Extending the cleanse beyond 10 days is not advised or necessary for results.

The 10-day timeframe is designed specifically to provide the benefits of the smoothie cleanse without causing harm to your health and metabolism.

Can You Do the JJ Smith Green Smoothie Cleanse Longer Than 10 Days?

It is generally not recommended to follow the JJ Smith green smoothie cleanse for longer than the prescribed 10 days. Here’s why:

  • Nutritional deficits – Green smoothies do not provide complete nutrition when consumed as your only food for an extended period. You may become deficient in protein, fiber or certain vitamins and minerals.
  • Metabolic slowdown – Severely restricting calories for too long can cause your metabolism to slow down to conserve energy. This makes it harder to lose weight.
  • Cravings and binges – Food restriction can lead to intense cravings. This increases the chance you will binge eat when the cleanse ends.
  • Fatigue – Some people feel weak or fatigued after 3-5 days of only smoothies. Energy levels can take a further hit if the cleanse is extended.

The 10-day limit is designed to provide optimal detox benefits without the downsides of following it longer term. Going beyond 10 days is not recommended or necessary. You can repeat the 10-day cleanse a few times per year if desired.

What to Expect When You Finish the JJ Smith Green Smoothie Cleanse

Once you complete the 10-day JJ Smith green smoothie cleanse, you can expect to feel lighter and more energetic. Many people report improved focus, sleep, mood, and digestion after the cleanse.

To keep these benefits going, it’s important to slowly transition back into a healthy diet. Here’s what you can expect after finishing the smoothie detox:

Potential Weight Loss

By replacing meals with low-calorie, nutrient-dense smoothies for 10 days, you can expect to lose a few pounds. Some of this will be water weight and waste product, so the number on the scale may fluctuate.

Reduced Cravings

The cleanse helps reset your taste buds and cravings. You may notice less desire for sugar, salt, coffee, and processed food after the detox.

Increased Energy

With your body less focused on digestion and eliminating toxins, you should feel more energized! Just beware of overexerting yourself post-cleanse.

Improved Focus

You may think more clearly and feel more focused once toxins and unhealthy foods are removed. This mental clarity should continue with a well-balanced diet.

Tip: Slowly Reintroduce Foods

Ease back into food over 2-3 days. Start with fresh fruits, salads, broths and light protein. Listen to your body to prevent digestive issues. Avoid inflammatory foods and unhealthy habits so you don’t undo your cleanse!


The JJ Smith green smoothie cleanse is designed to be followed for 10 days to detoxify, lose weight, and kickstart healthy habits. This timeframe provides the benefits of eliminating toxins and unhealthy foods without causing potential issues from following the restrictive cleanse for too long. While you may be eager for dramatic results, sticking to the recommended 10-day limit is best for your health.
